Propionic Acid: A Culprit in Obesity and Metabolic Dysfunction?

As promised on Tuesday, today is the last post in my continuing propionic acid series  as we wrap up not-celebrating the Biome Buzz’ official First Annual Propionic Acid week.  Today’s post is about just how suspect it is for all our health. A study…

Ameliorating the Adverse Effects of Excess Propionic Acid

I am officially declaring this Biome Buzz’ first annual Propionic Acid Week! (Unfortunately, this is not a cause for celebration.) If you remember, propionic acid (PPA) is a short-chain fatty acid produced by gut bacteria.  Ordinarily, PPA , like the other SCFAs, is great…

Is There Any Doubt Left that Propionic Acid is a Cause of Autism? Apparently not

I first started to write about autism and propionic acid (PPA) not long after creating this blog, back in the fall of 2016.  In January 2017, I described to you some of the work of Dr. Derrick MacFabe, which as particularly fascinated me for…

The Two Sides of Bacteroides fragilis

Back in May, 2018, I wrote about Bacteriodes fragilis (B. fragilis), a species of bacteria some strains of which are toxic, some of which are highly beneficial.  The main thrust of that post was about how our immune system, when functioning properly, can recognize…

Neurodegnerative and Neuropsychiatric Disorders: Prime Targets for Helminths

Within just a few weeks of each other, two papers have been published looking at the potential of using helminths to treat neurological conditions.  Not surprisingly, both focus on the powerful anti-inflammatory effect of helminths. (For those of you new to helminths:  these are…

Autism and Clostridia: Mounting Evidence of a Connection

As you know, I’ve been following the research of Dr. Derrick MacFabe for well over a decade now.  I’ve described it before on this blog, several times, including this first post 2 ½ years ago – to which, if you remember, Dr. MacFabe was…

Constipation, Dysbiosis, Autism and a Prebiotic: A New Clinical Trial

The single most common gastrointestinal (GI) complaint I hear as a nutritionist, by a long way, is constipation…and the single best piece of advice I give my clients is “drink more water.”  It never ceases to amaze me how dehydrated most people are.  Invariably,…

Helminth Therapy: A Call to Action

An interesting opinion piece by Dr. William Parker, of Duke University, and colleagues at a couple of Czech Universities, just appeared in Trends in Parasitology.[i]  To summarize, the paper makes two key points: A.  These scientists hold the belief that the interaction between human…

Transferring Autism Via Microbiota Transplant: A Clinical Study

In recent years, researchers have found they that by transferring the gut microbiome from animal to animal, they can also transfer particular “disease” states.  Take obesity, for instance – just one example of many – researchers transferred the gut microbiota from lean mice fed…

A Quick Update on the Mycobiome and Inflammatory Bowel Disease

A great article appeared last week on Gut Microbiota for Health,[i] on the overlooked mycobiome in digestive diseases.  I’ve written about this topic several times before and am always very happy to see new research focused on the topic. The authors of the paper[ii]…
